EPDM Rubber Gaskets - WRAS / WRc Approved

WRAS / WRc approved EPDM rubber gaskets are cut from a synthetic elastomer that meets the requirements of BS 6920-1:2000 and BS 6920-1: 2014 for use with wholesome water up to +23°C. These gaskets provide excellent resistance to weathering, ageing and ozone characteristic of EPDM whilst meeting stringent drinking water safety standards. Water authorities and utilities companies commonly specify these gaskets for sealing applications involving public drinking water infrastructure, ensuring compliance with health and safety regulations. The certification guarantees that no harmful substances leach into the water supply, making these gaskets essential for water treatment facilities, distribution networks and storage systems. Beyond drinking water applications, these gaskets deliver outstanding environmental resistance for general industrial use.

WRAS-approved EPDM gaskets have a cloth impression on both sides as standard and can be supplied with a plate finish if required. If industry standards are not critical to your application, we can supply standard EPDM rubber gaskets.

We have the capability to manufacture bespoke and standard table flange gaskets using CNC machinery. If you require help to accurately measure your gasket dimensions, please view our easy-to-read guide on ' How to Measure a Gasket '.
